Shortwave diffraction by an oblate spheroid
Journal of Soviet Mathematics, 1978The diffraction of shortwaves emitted by a point source located on the equator on an oblate spheroid is investigated by a three-dimensional analog of Watson's method. The zone of deep shadow is considered under the assumption that the point of observation is near the source and is either on the surface of the spheroid or near this surface.

Null tests for oblate spheroids
Applied Optics, 1984In most real cases requiring simple null optics, the optical path difference cannot be reduced to zero but can be kept at a fractional wavelength level so that interferometric data reduction can be used to account for the residual error. In other cases, computer-generated holograms may be used to obtain apparently straight fringes when the desired ...

Analysis of oblate spheroidal antenna
Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002An oblate spheroidal antenna with linearly polarized excitation is analyzed numerically, and its radiation patterns are examined. The beamwidth of the E-plane radiation pattern becomes wider as the antenna height is increased. The integral equation method can be easily applied to the case of circularly polarized excitation. >

Path instabilities of oblate spheroids
Journal of Fluid Mechanics, 2017In the present paper, we investigate the path instabilities and the transition scenario for oblate homogeneous spheroids falling (or ascending) freely in a quiescent and unconfined Newtonian fluid under the action of gravity, buoyancy and hydrodynamic forces. The problem depends on three independent external parameters: the aspect ratio $\unicode[STIX]{

Inverse Source Problem in an Oblate Spheroidal Geometry
IEEE Transactions on Antennas and Propagation, 2006The canonical inverse source problem of reconstructing an unknown source whose region of support is describable as a spheroidal (oblate or prolate) volume from knowledge of the far-field radiation pattern it generates is formulated and solved within the framework of the inhomogeneous scalar Helmholtz equation via a linear inversion framework in Hilbert

International Journal of Fracture, 1982
This paper contains a three-dimensional elastic solution for a region bounded by two oblate spheroidal surfaces, subjected to axisymmetric internal or external pressure. In the analysis, Boussinesq's two harmonic stress functions approach is employed and the solution is given in the form of a series involving Legendre functions expressed by oblate ...
